Bauxite is processed in alumina refineries by the bayer process in which al-containing minerals are dissolved in hot naoh. the insoluble solids (bauxite processing residue mud and sand) are washed, sometimes partially neutralized (using co2 or seawater treatment), and deposited in impoundments surrounding the refinery using either wet (15–30% solids) or dry (50–65% solids) disposal techniques.
